Alloy sand enters the impeller 72 through the material inlet pipe 74, and then the impeller 72 drives the alloy sand to perform variable acceleration centrifugal motion, so that the alloy sand moves to the edge of the impeller 72 and is thrown out, the moment when the alloy sand enters the impeller 72 can be adjusted by adjusting the opening direction of the hole 751, and the throwing angle of the alloy sand is controlled.

The working principle of the invention is as follows: when a hanger to be cleaned is hung on the hook 33 of the hanger 30, the shot blasting machine 1 is started, the hanger 30 drives along with the hanger from the first running rail 21, the hanger runs into the third running rail 23 through the left running rail 51, after the hanger is sent to a designated point in the shot blasting box 10, the box door 11 is closed, then the hanger 30 rotates in the chain 13, and then the dust removing device 80, the feeding device 60 and the shot blasting device 70 are started in sequence.

After the shot blasting machine 1 is started, the feeding device 60 sends the mixture in the shot blasting machine to the separator 64 for material-slag separation, clean alloy sand flows into the storage chamber 65 for short storage, then the alloy sand enters the shot blasting device 70 through the hose 66 and the material inlet pipe 74, is thrown out at a high speed through the blades of the impeller 72 and is hit on the surface of the hanger, and the coating film on the surface of the hanger can be broken through kinetic energy impact generated by the alloy sand, so that the cleaning effect is achieved. Dust generated in the cleaning process is collected through the dust removing device 80, so that the dust is prevented from diffusing out of the shot blasting machine 1 to cause environmental pollution.

After cleaning, the shot blasting device 70, the feeding device 60 and the dust removing device 80 are sequentially closed, then the box door 11 is opened, the hanger 30 returns to the original first travelling rail 21 with the processed hanger, at this time, the other hanger 30 starts from the second travelling rail 22, travels into the third travelling rail 23 through the right travelling rail 52, and repeats the above operation.
